Unvented Natural Gas Vent Free Room Heaters
FRESH AIR FOR COMBUSTION AND VENTILATION
WARNING: This heater shall not be installed in a confined
space or unusually tight construction unless provisions are
provided for adequate combustion and ventilation air. Read
the following instructions to insure proper fresh air for this
and other fuel-burning appliances in your home.
ESTABLISHING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas Code,
NFPA 54/ ANSI Z223.1, Section 5.3, Air for Combustion and
Ventilation. All spaces in homes fall into one of the three
following ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
This heater must not be installed in a confined space
or unusually tight construction unless provisions are
provided for adequate combustion and ventilation air. The
information on pages 4 and 5 will help you classify your
space and provide adequate ventilation.
Unusually Tight Construction
If your home meets all of the three following criteria you
must provide additional fresh air. See Ventilation from
Outdoors, page 5.
Unusually tight construction is defined as construction
where:
a. Walls and ceilings exposed to the outside atmosphere
have a continuous water vapor retarder with a rating
of one perm (6 x 10- 11 kg per pa-sec-m2) or less with
openings gasketed or sealed and
b. Weather stripping has been added on operable windows
and doors, and
c. Caulking or sealants are applied to areas such as joints
around windows and door frames, between wall-
ceiling joints, between wall panels, at penetrations
for plumbing, electrical, and gas lines, and at other
openings.
If you home does not meet all of the three criteria above,
see Determining the Type of Heater Location Space, below.
Confined Space and Unconfined Space
The National Fuel Gas Code, NFPA 54/ ANSI Z223.1
defines a confined space as a space whose volume is less
than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kW)
of the aggregate input rating of all appliances installed in
that space, and an unconfined space as a space whose
volume is not less than 50 cubic feet per 1,000 Btu per
hour (4.8 m3 per kW) of the aggregate input rating of all
appliances installed in that space. Rooms communicating
directly with the space in which the appliances are
installed*, through openings not furnished with doors, are
considered a part of the unconfined space.
*Adjoining rooms are communication only if there
are doorless passageways or ventilation grills between
them.

SAFETY DEVICE
This heater has a pilot with an Oxygen Depletion Sensor
(ODS) safety shut off system. The ODS/pilot shuts off the
heater if there is not enough fresh air.
IGNITION SYSTEM / BATTERY INSTALLATION
PIEZO: The heater is equipped with an electronic manual
igniter. This system requires no matches, batteries, or other
source to light heater but does require one AA battery to
operate igniter.
To install or replace battery unscrew the igniter cap (red
button), insert battery positive (+) terminal up and replace
cap. (AA Battery included)
THERMOSTATIC CONTROL
These heaters have a control valve with a thermostat
sensing bulb. This results in the greatest heater comfort
and may result in lower fuel bills.
BLOWER FAN CONTROL SWITCH OPERATION
(If Equipped)
The blower switch has three positions: MANUAL, OFF and
AUTO. In AUTO, the blower will turn on and off as the
heater cycles on and off. On MANUAL, the blower will run
continuously. To turn blower off, use the OFF position.
LOCAL CODES
Install and use heater with care.
Installation must conform to local codes or in the absences
of local codes, use the latest edition of National Fuel Gas
Code, ANSI Z223.1/NFPA 54.
UNPACKING
1. Remove heater from carton.
2. Remove all protective packaging applied to heater
for shipment.
3. Check heater for any shipping damage. If heater
is damaged, promptly inform dealer where you
bought heater.

Unvented Natural Gas Vent Free Room Heaters
DETERMINING THE TYPE OF HEATER LOCATION
SPACE:
Use this method to determine if you have a confined or
unconfined space.
Note: the space includes the room in which you
install heater plus any adjoining rooms with doorless
passageways or ventilation grills between the rooms.
1. Find the volume of the space by multiplying room length
x width x height.
Example: Space size 18ft (length) x 18ft. (width) x 8ft.
(height) = 2592
If additional ventilation to adjoining room is supplied with
grills or openings, add the volume of these rooms to the
total volume of the space.
2. Divide the space volume by 50 cubic feet to determine the
maximum Btu/hr the space can support.
Example: 2592 cu.ft. (volume of space) / 50 cu.ft. =
51.8 or 51,800 (maximum Btu/hr the space
can support)
WARNING: This heater shall not be installed in a
room or space unless the required volume of indoor
combustion air is provided by the method described
in the National Fuel Gas Code, ANSI Z223.1/NFPA 54,
the International Fuel Gas Code, or applicable local
codes
3. Add the Btu/hr of all the fuel-burning appliances in the
space such as, Vent–free heater, Gas water heater, Gas
furnace, Vented gas heater, Gas fireplace logs, and Other
gas appliances*
*Do not include direct-vent gas appliances. Direct-vent
draws combustion air from the outdoors and vents to
the outdoors.
Example:
Gas water heater 40,000 Btu/hr
Vent Free Heater + 20,000 Btu/hr
Total =60,000 Btu/hr
4. Compare the maximum Btu/hr the space can support
with the actual amount of Btu/hr used.
Example: 51,800 Btu/hr (maximum Btu/hr the
space can support)
60,000 Btu/hr (Actual amount of Btu/hr used)
The space in the above example is a confined space
because the actual Btu/hr used is more than the
maximum Btu/hr the space can support.
You must provide additional fresh air. Your options are
as follows:
A. Rework worksheet, and the space of an adjoining room.
If the extra space provides an unconfined space, remove
door to adjoining room or add ventilation grills between
the rooms. See Ventilation From Inside Building (Fig. 2)
B. Vent room directly to the outdoors. See Ventilation From
Outdoors (Fig. 3).
C. Install a lower Btu/hr heater if lower Btu/hr size makes
room unconfined.
If actual Btu/hr used is less than the maximum Btu/
hr the space can support, the space is an unconfined
space. You will need no additional fresh air ventilation.
VENTILATION AIR
Ventilation from Inside Building
This fresh air would come from an adjoining unconfined
space. When ventilation to an adjoining unconfined space,
you must provide two permanent openings: one within 12”
of the ceiling and one within 12” of the floor on the wall
connecting the two spaces (see options 1 & 2 of figure 2).
You can also remove door into adjoining room (see option3,
fig 2). Follow the National Fuel Gas Code NFPA 54/ ANSI
Z223.1, Section 5.3, Air for Combustion and Ventilation for
required size of ventilation grills or ducts.
WARNING: Rework worksheet, adding the space of
the adjoining unconfined space. The combined space
must have enough fresh air to supply all appliance in
both spaces.
Ventilation from Outdoors
If necessary provide extra fresh air by using ventilation grills
or ducts. Connect these items directly to the outdoors or
spaces open to the outdoors. These include attics* and
crawl spaces. Follow the National Fuel Gas Code NFPA
54/ ANSI Z223.1, Section 5.3, Air for Combustion and
Ventilation for required size of ventilation grills or ducts.

Note: Use of floor mounting feet will require you to use
a 3/8 NPT street elbow to make gas connection.
CONNECTING TO GAS SUPPLY
WARNING: A qualified service person must connect
heater to gas supply. Follow all local codes.
WARNING: This appliance requires a 3/8” NPT
(National Pipe Thread) inlet connection to the pressure
regulator. Use of floor mounting feet will require you
to use a 3/8 NPT street elbow to make gas connection.
CAUTION: Never connect heater to private (non-utility)
gas well. This gas is commonly known as well-head
gas.
IMPORTANT: Check your gas line pressure before
connecting heater to gas line. Gas line pressure must
be no greater than 14 inches of water. If gas line
pressure is higher, heater regulator damage could
occur.
CAUTION: Use only new black iron or steel pipe. Internally-
tinned copper tubing may be used in certain areas. Check
your local codes. Use pipe of large enough diameter to
allow proper gas volume to heater. If pipe is too small,
undue loss of pressure will occur.
Installation must include an equipment shutoff valve, union
and plugged 1/8” NPT tap. Locate NPT tap within reach of
test gauge hookup. NPT tap must be upstream from heater
(see figure 12).
9Installation Instructions and Owner’s Manual
Unvented Natural Gas Vent Free Room Heaters
*A CSA/AGA certified equipment shutoff valve with
1/8” NPT tap is an acceptable alternative to test gauge
connection. Purchase the CSA/AGA certified equipment
shutoff valve from your dealer.
IMPORTANT: Install an equipment shutoff valve in an
accessible location. The equipment shutoff valve is for
turning on or shutting off the gas to the appliance.
Apply pipe joint sealant lightly to male threads. This will
prevent excess sealant from going into pipe. Excess sealant
in pipe could result in clogged heater fuel train.
CAUTION: Use pipe joint sealant that is resistant to
Natural Gas.
Install sediment trap in supply line as shown in figure 12.
Locate sediment trap where it is within reach for cleaning.
A sediment trap traps moisture and contaminants. This
keeps them from going into heater. If sediment trap is
not installed or is installed improperly, heater may not run
correctly.
IMPORTANT: Hold pressure regulator with wrench when
connecting it to gas piping and/or fittings.

shock hazard and should be plugged into a properly
grounded three prong receptacle.
OPERATING YOUR HEATER
FOR YOUR SAFETY READ BEFORE LIGHTING
WARNING: If you do not follow these instructions
exactly, a fire or explosion may result causing property
damage, personal injury or loss of life.
A. This appliance has a pilot that must be lighted by hand.
When lighting the pilot, follow these instructions exactly.
B. BEFORE LIGHTING smell all around the appliance area
for gas. Be sure to smell next to the floor because some
gas is heavier than air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS
• Shut off gas supply.
• Do not try to light any appliance.
• Do not touch any electrical switch; do not use any
phone in your building.
• Immediately call you gas supplier from a neighbor’s
phone. Follow the gas supplier’s instructions.
• If you can not reach your gas supplier, call the fire
department.
C. Use only your hand to push in or turn the gas control knob.
Never use tools. If knob will not push in or turn by hand,
don’t try to repair it; call a qualified service technician or gas
supplier. Force or attempted repair may result in a fire or
explosion.
D. Do not use this appliance if any part has been
underwater. Immediately call a qualified service
technician to inspect the appliance and to replace any
part of the control system which has been under water.
LIGHTING INSTRUCTIONS
1. STOP! Read the all safety information included with and
on the side of heater.
2. Check that gas supply to heater is on.
3. Push in gas control knob and slightly turn clockwise to the
OFF position (see figure 16).

4. Wait five (5) minutes to clear out any gas. Then smell
for gas, including near the floor. If you smell gas, STOP!
Follow “B” in the safety information above. If you do not
smell gas, go to the next step.
5. Turn counterclockwise to PILOT/IGN, if knob does
not turn then slightly depress and turn. Once knob is in
PILOT/ IGN depress for five (5) seconds.
Note: The first time that the heater is operated after
11 Installation Instructions and Owner’s Manual
Unvented Natural Gas Vent Free Room Heaters
connecting the gas supply, the control knob should be
depressed for about 30 seconds. This will allow air to bleed
from the gas system.
6. With control knob pressed in, push down and release
the ignition button. This will light pilot. If needed keep
pressing igniter button until pilot lights.
7. Keep control knob pressed in for (30) seconds after
lighting pilot. After 30 seconds, release control knob.
• If pilot does not stay lit, refer to Troubleshooting, pages
12-13. Also, contact a qualified service person or gas
supplier for repairs.
• If control knob does not pop up when released, contact
a qualified service person or gas supplier for repairs.
8. When the pilot is lit, turn the control knob
counterclockwise to heating level. The main burner
should light.
9. To select the desired heat level, turn the temperature
setting knob to desired comfort setting from 1 to 5.
CAUTION: Do not try to adjust heating level by using
equipment shutoff valve.
TO TURN OFF GAS TO APPLIANCE
SHUTTING OFF HEATER:
1. Turn off equipment shutoff valve.
2. Turn control knob clockwise to the OFF
position.
SHUTTING OFF BURNER ONLY (PILOT STAYS LIT)
1. Turn control knob clockwise to the PILOT/IGN
position.
THERMOSTAT CONTROL OPERATION
FOR HSSVFRD20NGBT / HSSVFRD30NGBT:
The thermostatic control used simply turns on and off the
burner.
FOR HSSVFBF20NGBT / HSSVFBF30NGBT:
The thermostatic control used modulates the flame size as
the temperature gets closer to set point, then it turns off
the burner upon reaching temperature.
The burner will cycle back on when room temperature
drops below the set temperature. The control knob can
be set to any heat level between 1 and 5. Selecting the HI
setting will cause the burner to remain on.
INSPECTING BURNER
Check pilot flame pattern and burner flame pattern often.
PILOT FLAME PATTERN
Figure 17 show a correct pilot flame pattern and also shows
an incorrect pilot flame pattern. The incorrect pilot flame
pattern is not touching thermocouple. This will cause the
thermocouple to cool. When the thermocouple cools, the
heater will shut down. If pilot flame pattern is incorrect, as
shown in Figure 17:
• Turn heater off (see To Turn OFF Gas to Appliance,
page 10)
• See Troubleshooting, pages 12-13.

CLEANING AND MAINTENANCE
WARNING: Turn off heater and let cool before
servicing.
For maintenance of the inside cabinet or to access the burner
and pilot assembly for cleaning or service. Remove the four
screws(two located on each side) that secure the front shell
to the unit (Figure 6). Gently lift up on the front shell to
disengage the hooks and pull forward to remove it. You will
now be able to access all of the internal components of the
appliance.
CAUTION: You must keep control areas, burner and
circulation air passageways of heater clean. Inspect these
areas of heater before use. Have the heater inspected
yearly by a qualified service person. Heater may need more
frequent cleaning due to excess lent from carpeting, bedding
material, pet hair, etc.
Make sure grille guard is in place before running heater. If
screen or grille guard is removed for servicing it must be
replaced prior to operating the heater.
WARNING: Failure to keep the primary air opening(s)
of the burner(s) clean may result in sooting and
property damage.
CLEANING ODS/PILOT AND BURNER
• Use as vacuum cleaner, pressurized air or small soft
bristled brush to clean.
CLEANING BURNER PILOT AIR HOLE INLET
We recommend that you clean the unit every 2,500 hours of
operation or every three months. We also recommend that
you keep the burner tube and pilot assembly clean and free
of dust and dirt. To clean these parts we recommend using
compressed air no greater than 30 psig.
This can be done by using a vacuum cleaner in the blow
position or using compressed air in a can. If using canned air
please follow the directions on the can. If you don’t follow
directions on the can you could damage the burner or pilot
assembly. In addition, the directions below should also be
followed.
1. Shut off the unit, including the pilot. Allow the unit
to cool for at least thirty minutes.
2. Inspect burner and pilot for dust and dirt.
3. Blow air through the port/slots and holes in the
burner.
A yellow tip on the pilot flame indicates dust and dirt in the
pilot assembly. To clean the pilot assembly find the small pilot
air inlet hole about two inches from where the pilot flame
comes out of the pilot assembly (see figure 18). With the unit
off, lightly blow air through the air inlet hole. You may blow
through a drinking straw if compressed air is not available.
